Guan Feng said, "The sound is too soft, it's normal that you can't hear it. The technical team will process it later and you'll be able to hear it."

Wang Xun said, "Okay, I'll contact Captain Chen."

Guan Feng said, "Don't make this public for now. If the other party can really sneak in silently, it means they have a very good understanding of the hospital's layout."

Wang Xun asked, "Captain, do you suspect an inside job?"

Guan Feng said, "It's hard to say whether they're insiders or not, but at least they have insiders providing support."

Wang Xun contacted Chen Xuewen with a serious expression.

A moment later.

Chen Xuewen walked in.

"Captain Guan, you were looking for me?"

Guan Feng nodded and explained his demands to the other party.

Chen Xuewen put on the headset, listened for a while, glanced at Guan Feng in surprise, and nodded, saying, "Amplification is no problem, but are you sure there's a door opening sound?"

Guan Feng said, "Let's zoom in first."

Chen Xuewen then instructed his team members to copy the audio files and amplify the sound using special technology.

A moment later.

The group put on their headsets and began listening.

This time!

The whirring of the air conditioner seemed almost within reach, and as time passed, the creaking sound of a door opening clearly reached their ears.

Wang Xun put down the headset and asked in surprise, "There really is?"

Chen Xuewen looked at Guan Feng with admiration and said, "Captain Guan, sometimes I wonder if your body structure is different from ordinary people? I checked, and the sound before it was amplified was 0.03 decibels. Most people would definitely not be able to hear it clearly, but you can hear it clearly?"

Guan Feng said, "It's a coincidence! I only felt something was wrong when I listened to it the first time, but I only realized the problem after listening to it several times."

Wang Xun said, "Captain, don't be modest. I think you were already certain, which is why you had Captain Chen amplify the audio."

Guan Feng waved his hand and said, "Let's find out how the other party got into the morgue before we start talking!"
